Malpighian tubules


Malpighian tubules

This illustration is inspired by the excretory and osmoregulatory system of insects—and other arthropods—called Malpighian tubules. These tubules are connected to the hindgut, where they dump their waste products. The artwork shows a detail of a tubule of the fruit fly, Drosophila melanogaster, which is composed of two different cell types: principal cells (not colored) and stellate cells (orange tones). The former fulfills the function of regulating the ionic balance whilst the latter is essential for the water balance. This image was used to illustrate the Doctoral Thesis of Lautaro Gándara.
